Question 1

What is this Calibre deployment?

Accepted Answer

It is the full Calibre desktop application — the definitive e-book management tool — running inside your browser via KasmVNC, rather than a lightweight web app. You get every desktop feature: importing and organising books, bulk metadata editing, format conversion, direct file editing, and more, with the library living on your server. The GUI runs on port 8312 and Calibre's content server, for reading and downloading, on port 8313.

Question 2

How is it different from calibre-web?

Accepted Answer

calibre-web is a separate, lighter tool that provides a clean web interface for browsing and reading an existing Calibre library, but it does not manage or convert books. This full Calibre install is the management engine — where you actually build, organise, and convert the library. Many people run both: full Calibre as the powerful back-office, and calibre-web as the pleasant everyday reading front-end pointed at the same library.

Question 3

Which ports does it use?

Accepted Answer

Two: the Calibre desktop GUI on host port 8312, streamed via KasmVNC, and Calibre's built-in content server on host port 8313 for reading and downloading books over the network. The GUI is effectively a remote desktop, so put it behind a reverse proxy with TLS and authentication and never expose it in plain form. Secure the content server too if your library should stay private.

Question 4

Why does it use KasmVNC?

Accepted Answer

KasmVNC is what lets the real Calibre desktop application run in a browser: instead of reimplementing Calibre as a web app and losing features, the image streams the actual desktop GUI to your browser, so you keep Calibre's complete capabilities. The trade-off is that streaming a full desktop uses more resources and feels like a remote desktop rather than a native web UI, which is the cost of having the whole application available remotely.

Question 5

Can I read my books on other devices?

Accepted Answer

Yes — that is what the content server on port 8313 is for. Once enabled, it lets you browse, read, and download your library from other devices and from e-reader apps over the network. Many people also run calibre-web against the same library for a nicer reading interface. So you manage and convert with full Calibre, and read across your devices through the content server or calibre-web.
